| 摘 要： | 采用金相显微镜、扫描电镜，透射电镜对冷弯断裂钢筋的断口进行了分析，结果表明，钢筋断裂的主要原因是弯曲时弯心太小，不符合标准要求，不是钢筋本身质量所致。

| Abstract: | The analysis has been taken on fracture by means of optical metallographic microscope, scaning electron microscope and transmission electron microscope. The results show that the cracking is chiefly caused by too small bending core fallen short of criterion, not by the quality of the hot rolled ribbed bars. |
